Application filed July 14, 1919. Serial No. 310,833. l

veyers, of which the following is a specica- Q tion, reference being had therein to the accompanying drawings.

The invention relates to conveyers of that type in which the load is carried by a trolley traveling upon a track which is bent orcurved in transverse planes. It is the object of the invention to permit freedom of movement in conformity to the contour of the track and at the same time' to support the load without lateral stress upon the conveyer chain. It is a further object to permit of supporting the load at points intermediate the trolleys without lateral stress upon the chain. With these objects in view the invention consists in various features of forth.

In the drawings: Figure 1 is a sidejelevation; Figure 2 is a cross-section; Figure 3 is a plan view. A is a track which, as specifically shown,

comprises a pair of spaced parallel rails.

B are trolley wheels for traveling onthe rails A being provided with the flanges C for preventing lateral displacement andbeing mounted upon a non-revoluble axle D.

E is a hanger clamped upon the central portion of the axle D and depending therefrom between the rails of the track A. rIvhe hangers E are connected to each other through a series of links F, which `are pivotally connected at G to swing in`a plane transverse to the plane f rotation vof the wheels.

There is also provided'a pivotal connection H between the links and one of said hangers, v

permitting. a swinging movement in the plane of rotation of the wheels'. Thus, in the specific construction shown, the hanger Ehas projecting laterallyl therefrom the lug I with which one of the links F is connected .by a pin Gr. While upon they opposite side of the-hanger, the link F' is conv nected with another of the links F through the medium of alink J and the transverselyextending pin H Below the lug I is a bifurcated extension Kl on the hanger for supporting a hook Lto which the load is attached. u

.the trolleys.

For certain 4uses,lit is desirable to provide suspension means for the load intermediate If such suspension devices were attached` directly tothe chain, it would throw an objectionable lateral stress thereon and upon the connecting pivots G. I have, therefore, provided intermediate the hangers rigid longitudinally-extending bearings M which are connected to the depending portion of the hangers E through the medium of links N and O. Along the bars M are arranged a series of hooks P similar to the hooks L and so spaced as to provide for engagement with the load wherever desired. These hooks are preferably connected by providing a pair of bars M loe-- tween which the eyes of the hooks are arranged to engage cross beams Q.

In use, when the track A is bent in a Vertical plane, the pivot pins H will-permit an angular movement ofthe chain sections intermediate the hangers E; on the other hand, where the track is ,bent or curved in a horizontal plane,l the pivots G connecting adjacent links will permit of the corresponding bending of the chain. Where the load is supported by the hooks L, the weight will be carried by thel trolleys B through the medium of the hanger E, vbut'if the load is suspended from any one of the intermediate hooks P, the stress willlbe transmitted through the vlinks M and O to the adjacent hangers E without @any lateral stress upon the intermediate portion of the chain. It will also be understood lthat when the chain is bent or curved in horizontal` y* What I claim as my invention is:

1. In a conveyer, the combinationwith a series of trolley wheels mounted thereon, of

2. In a conveyer, the combination with a.

series of trolley wheels, of'hangersdependlng from said-trolley wheels provided with meansfor attachment of a load thereto, land' a link chain, connecting said hangers, the

portion thereofvintermediate said hangers,

In a conveyer, the combination with a series of trolley wheels, of hangers depending from said wheels and provided with means for attachment of a load thereto, a link chain connecting said hangers comprising a series of links intermediate adjacent hangers pivotally connected to each other to swin in a path transverse to the plane of rotation of said trolley wheels and being pivotally connected to one of said hangers to swing in a path parallel to the plane of rotation.

4. In a conveyer, the combination with a' track bent or curved in transverse planes,

of a series of trolley wheels for traveling on. said track, hangers depending from said trolley wheels and provided with means for attachment of a load thereto, anda link chain connecting said hangers, the portions intermediate adjacent hangers comprising a y plurality of links pivotally connected to one of the hangers in a plane transverse to the plane of rotation of thel trolley wheels and pivotally connected t-o the opposite hanger in a plane parallel to the plane of rotation of said wheels, a rigid load-carrying member extending between' adjacent hangers and supported thereby, and means of attachment between said rigid load-supporting member and hangers permitting limited relative movement of the hangers.

5. In a conveyer, the combination with a track bent or curved in transverse planes, of a series of trolle wheels traveling upon said track, hangers epending from said trolley wheels, a link chain connecting said hangers, the portion thereof intermediate adjacent hangers comprising a plurality of links pivotally connected to each other, and one of the hangers'in a plane transverse to the plane of rotationto said wheels and pivotally connected to the -opposite hanger in a plane parallel to the plane of rotation of said wheels, a load-carrying bar extending between hangers and supported therefrom, and links forming the supporting connection for said bar from said hanger permitting limited relative adjustment of the-latter.

6. In a conveyer, the combination with a trolley wheel, of a hanger depending therefrom and provided lat its lower end with means for attachment of a load thereto, a`

link chain connecting said hanger with similar hangers, the portion of said chain on one side of said hanger being pivotally attachedthereto to swin in the plane of rotation of said trolley w eel, and the portion' on the` opposite side of said hanger beingv pivotally connected thereto to swing in a plane transverse to the plane of rotation of said wheel. n

7. In a conve er, the combination with a trolley wheel, o a hanger depending therefrom having a hook at its lower end for attachment of a load and a laterally extending portion intermediate its ends, a link chain connected to said hanger with a portion on one side thereof attached to said laterally extending portion andl pivoted to swing in a plane 'transverse to the plane of `rotation of said trolley wheel and the'portionfupon the opposite side of said hanger being pivoted thereto to swing in a plane parallel to the plane of rotation of said wheel. v
